Review on πŸ’§ Convenient Manual Hand Pump for Water Coolers - Blue Gray Thickened Pressure Pump with Short Tube & Cap by Jon Larjin

Revainrating 3 out of 5

That works fine. best for rough plumbing

It works but not very efficient. It doesn't suck the water out of the bottle like a pump dispenser mechanism, but instead forces air into the bottle to cause the water to rise up and out of the nozzle. Unfortunately, this means a tight bottle seal is REQUIRED, and the looser the seal, the less effective it is as air escapes rather than displacing water.

Pros
  • This is amazing
Cons
  • Negative impression
